FAQ
How many kinds of timeout intervals can be chosen in the Watchdog Timer (WDT) controller? Issue Date:2015-02-09
There are eight kinds of timeout intervals provided in the WDT controller. Also, the WDT controller has multiple clock sources including 10 kHz and HCLK/2048.
The following table shows the formula of WDT timeout intervals with 10 kHz and HCLK/2048 clock sources.
Level |
Timeout interval |
WDT_CLK = 10 kHz |
WDT_CLK = HCLK/2048 |
0 |
24 × TWDT_CLK |
24 × 100μs = 1.6 ms |
24 × (2048/HCLK) |
1 |
26 × TWDT_CLK |
26 × 100μs = 6.4 ms |
26 × (2048/HCLK) |
2 |
28 × TWDT_CLK |
28 × 100μs = 25.6 ms |
28 × (2048/HCLK) |
3 |
210 × TWDT_CLK |
210 × 100μs = 102.4 ms |
210 × (2048/HCLK) |

212 × TWDT_CLK |
212 × 100μs = 408.6 ms |
212 × (2048/HCLK) |
5 |
214 × TWDT_CLK |
214 × 100μs = 1.6384 s |
214 × (2048/HCLK) |
6 |
216 × TWDT_CLK |
216 × 100μs = 6.5536 s |
216 × (2048/HCLK) |
7 |
218 × TWDT_CLK |
218 × 100μs = 26.2144 s |
218 × (2048/HCLK) |
WDT_CLK is the clock source of WDT controller:
TWDT_CLK = 1 / WDT_CLK
